A soft headband with embedded sensors.
Scent reaches the brain through its oldest pathway, the one wired directly to emotion and memory, before conscious thought catches up. It's why a fragrance can return you to a moment you'd forgotten.
We read that response as it happens. Four sensors rest against your forehead and pick up your brain's electrical rhythms, your brain waves, sampling many times a second as each scent unfolds. Your strongest, least-guarded reaction comes in the first few seconds, before you've decided what you think.
Every brain is different, so we don't compare you to anyone else. Your reading is measured only against your own baseline, the quiet state we record before we begin.
An honest note
ÉLYSIUS is an experience, not a diagnosis. We read how your brain responds to each scent, not a verdict on what you "should" love. Your senses, made visible.
